Termination of Registration Statement and
Deregistration of Securities
On December 22, 1999, the stockholders of Leukosite, Inc. (the
"Company") approved and adopted an Agreement and Plan of Merger, dated as of
October 14, 1999, by and among the Company, Millennium Pharmaceuticals, Inc.
("Millennium") and ANM, Inc., a wholly-owned subsidiary of Millennium (the
"Merger"). Because all of the shares of LeukoSite common stock which were
registered on the registration statement on Form S-3, No. 333-76173 (the
"Registration Statement"), have been sold prior to the Merger or have been
converted into shares of Millennium common stock in connection with the Merger,
no additional shares of LeukoSite common stock registered on the Registration
Statement can be sold or otherwise issued under the Registration Statement. As a
result, the Company hereby removes from registration any and all unsold shares
of LeukoSite common stock that were previously registered under the Registration
Statement, and hereby files this Post-Effective Amendment No. 3 to the
Registration Statement to effect such removal and to terminate the Registration
Statement.
